| Required record | Control |
|---|---|
| When the voucher was compiled and when the event occurred | Keep document and transaction dates separately if they differ. |
| What happened, amount and counterparty | Invoice, receipt, agreement, bank support and explanation must tell a reviewer what was booked. |
| Voucher number or other unique identifier | Link the identifier from source document to journal and ledger. |
| Account coding and accounting period | The continuous record must show registration order, period, voucher identifier, coding and booked amount. |
| VAT/payroll/tax classification evidence where relevant | Retain the tax evidence separately; a ledger account cannot establish tax treatment by itself. |
Use for tax year 2026 and the entity’s actual financial year. This method covers who must keep books, recording, vouchers, timing, reconciliation, correction, archiving and an ordinary K1/K2 annual close with its deadlines. It draws on the Book-keeping Act (BFL), the Annual Accounts Act (ÅRL) and BFN guidance.
The Book-keeping Act and Annual Accounts Act are the framework for Swedish accounting; BFN issues the guidance that expresses generally accepted accounting principles. BFN source
Use this method for the legal entity’s own Swedish activity. It does not select tax treatment, a BAS account number, VAT result, payroll calculation or specialised accounting policies outside the ordinary K1/K2 branches below. A BAS chart can be a useful internal mapping but is not a statutory substitute for a system that can show the required journal and ledger information.
Before processing entries, record:
A business event includes changes to the size or composition of assets caused by economic dealings with outsiders, including payments, receivables, liabilities and owner contributions/withdrawals. An order alone is not a business event. BFN source
For each event, create or retain a voucher that establishes:
| Required record | Control |
|---|---|
| When the voucher was compiled and when the event occurred | Keep document and transaction dates separately if they differ. |
| What happened, amount and counterparty | Invoice, receipt, agreement, bank support and explanation must tell a reviewer what was booked. |
| Voucher number or other unique identifier | Link the identifier from source document to journal and ledger. |
| Account coding and accounting period | The continuous record must show registration order, period, voucher identifier, coding and booked amount. |
| VAT/payroll/tax classification evidence where relevant | Retain the tax evidence separately; a ledger account cannot establish tax treatment by itself. |
A document received about the event must itself be used as the voucher, supplemented where needed. Bokföringslagen 5 kap. 6–7 §§ The BFN guide requires the core voucher information to be durable and not erased or made illegible. If an externally received voucher is incomplete, add missing information without changing the received content; record when, by whom and how it was supplemented. BFN source
Maintain both:
For each posting, those presentations must make available registration order, accounting period, voucher identifier, account coding and amount. Separate sales, purchase, payroll, cash and bank systems must feed one systematic accounting record; isolated ledgers are not enough. An event counts as booked only when it can be presented in both orders. BFN source
Cash receipts and cash payments (notes, coins, cheques and similar; in some cases paper meal vouchers and gift cards count as cash) must be booked for the registration-order presentation no later than the next working day. The next working day is the first day after the event on which work is performed in the business. If there are more than a few days between the event and that next working day, book by the day after the event. A shop closed on Sunday books Saturday's cash by Monday. BFN source
Other business events must be booked as soon as the entity has enough information to book them acceptably. Receivables and liabilities may wait until the invoice is issued or received (or commercially should have been); if used, apply this consistently during the year to both issued and received invoices. BFN source
Permitted deferral. Only if the vouchers are kept in order as they arrive, BFN allows booking later, at the latest: BFN source
These deferrals do not apply to cash for the registration-order presentation, which stays next working day. Two exceptions: cash recorded in a certified cash register may be booked in registration order up to 50 days after month end; and an entity that is book-keeping liable only under Bokföringslagen 2 kap. 2 or 3 § (non-profit associations, registered religious communities, joint-property associations, foundations and similar) whose cash receipts are normally below one price base amount a year may book cash in registration order up to four weeks after the event. For sales from a coin-operated vending machine, cash may be booked in registration order the day after the machine is emptied (or the day after the emptying company reports); machines must be emptied close to year end. Anything later is allowed only for a special obstacle of a temporary nature, such as acute illness, and then only for a day or a few days. BFN source
Payment-based (cash) method. An entity whose annual net turnover is normally at most SEK 3 million may wait to book business events until payment, but must book all receivables and liabilities still unpaid at the end of the financial year. This is not open to credit institutions, securities companies or insurance companies, or to financial holding companies that must prepare group accounts under those Acts. Vouchers must still be kept in order while waiting, and the month, quarter and year-end deferral windows in step 3 (BFN points 3.6–3.8) run from the payment date; the sole trader's tax-return date is not moved. This does not remove source-document, cash-record or closing obligations. Bokföringslagen 5 kap. 2 § BFN source
Complete each accounting period by reconciling relevant balances and posting corrections found in the reconciliation. Do not silently reopen a completed period.
Do not delete or make an original booked record illegible. In computerised bookkeeping, correct a booked posting with a separate correction posting. It is a new posting with its own voucher and must make the original and correction traceable. A manual record can only be struck through where it has not affected totals; otherwise use a correction posting. If the earlier period is completed, the correction belongs in the discovery period. If an error is found while reconciling an unfinished period, correct that unfinished period; do not confuse reconciliation performed the following month with a completed-period error. BFN source
When correcting a posting or a voucher, record when the correction was made and by whom. Bokföringslagen 5 kap. 5 och 9 §§ If a correction changes VAT, PAYE, tax return or filed financial-statement results, follow the separate return/amendment process as well; changing the ledger alone does not amend a filed tax return. BFN source
| Output | Deadline |
|---|---|
| Annual financial statements or simplified annual accounts | As soon as possible, and no later than six months after the financial year ends (four months for a foundation). Bokföringslagen 6 kap. 7 § |
| AB or economic association: annual report to the auditors | At least six weeks before the annual general meeting that deals with it. Other entities: within four months after year end. ÅRL 8 kap. 2 § |
| AB or economic association: filing with Bolagsverket | Certified copies of the annual report and audit report must reach Bolagsverket within one month after the meeting adopts the balance sheet and income statement. If they have not arrived within seven months after year end, a late-filing fee is charged: SEK 7,500 for a private AB or an economic association, SEK 15,000 for a public AB. The fee repeats: if the documents still have not arrived within two months after notice of the fee decision, a second fee is charged (SEK 7,500; public AB SEK 15,000), and if they are still missing two months after that notice, a third fee (SEK 15,000; public AB SEK 30,000). The seven months become nine months only if, within the seven months, the company has notified a continued meeting, paid its registration fee and filed the auditor's written confirmation. ÅRL 8 kap. 3, 5 och 6 §§ |
| Partnership with a legal-person partner; foundation | Copies to Bolagsverket (a foundation files with its supervisory authority) within six months after year end. A foundation that must file and misses the six months pays a SEK 7,500 late fee, with the same repeat fees (SEK 7,500, then SEK 15,000) if it still does not file. ÅRL 8 kap. 1, 3, 6 och 6 a §§ |
| Other entities preparing an annual report | Keep copies available to anyone from six months after year end; a larger company must file them with Bolagsverket within six months even without a request. ÅRL 8 kap. 3 § |
The meeting date itself, and the tax-return dates, come from company law and the tax rules, not from this method; confirm them for the entity before relying on a date.
Keep accounting information durable, easily accessible, orderly and secure in Sweden up to and including the seventh year after the end of the calendar year in which the financial year ended. Keep the equipment and systems needed to print it out on paper available in Sweden for the whole period. The Sweden rule does not apply to records of a foreign branch with its own administration if the company is book-keeping liable in that other country. Bokföringslagen 7 kap. 2 och 5 §§
For electronic records, make regular backups suited to the business’s volume and keep a backup separate from the copied records. Maintain an archive plan where needed that says what is stored, where it is stored and how the archive is structured. A cloud provider or accountant may hold data, but the book-keeping entity must retain access during the full archive period, including after a software/provider change; an online bookkeeping service that stores the data abroad is foreign storage and triggers the notification above. BFN source
Maintain system documentation and processing history sufficient for an external reviewer to understand the chart/account mapping, voucher identification, data flows, automated posting rules and how electronic records can be produced. A spreadsheet whose entries can be changed afterwards, such as Excel, is not an acceptable bookkeeping system for a sole trader. BFN source BFN source
Use the whole selected framework consistently. This section covers a normal sole trader using K1 and an eligible smaller private limited company using K2. A different legal form, K3 or a regulated financial entity needs its own framework. The linked consolidated K1 and K2 editions contain the current changes; select by the financial year’s start date rather than assuming that the filing year alone selects the rules. BFN current guide catalogue
A sole trader (a natural person, not the parent of a group; an estate carrying on business counts as a natural person) whose net turnover across all of the person's businesses is normally at most SEK 3 million may choose simplified annual accounts. A person with several businesses may use K1 only if it is applied to all of them. Use the K1 balance-sheet and income-statement layout, with its own recognition rules rather than borrowing K2 accrual simplifications. K1
First establish that the entity is smaller under the Annual Accounts Act. A larger company is a listed company, or one that meets more than one of these in each of the two latest financial years: more than 50 employees on average, a balance-sheet total of more than SEK 40 million, net turnover of more than SEK 80 million. ÅRL 1 kap. 3 § BFN framework selection
K2 excludes public limited companies; parents of larger groups; parents preparing consolidated accounts; individuals/estates; housing associations; businesses with foreign branches during the year; acquisitions of goods/services for share-based consideration; issued convertible or similar compound financial instruments; and crypto holdings during the year other than occasional use/receipt as payment. K2 scope
It also excludes material deferred-tax-liability cases and buildings generating at least 75% of turnover, subject to the specific small-entity and temporary-condition exceptions. Assess these additional exclusions using the latest financial year for which a completed annual report exists. The small-entity exception applies where no more than one of these is exceeded in each of the two preceding years: employees 3, balance sheet SEK 1.5 million, net turnover SEK 3 million. The other exception requires K2 in the preceding year and conditions not normally falling within those additional exclusions. These exceptions do not override the preceding exclusion list. Document the screen and source financial statements. K2 scope
A new business starting after June 2025 with an extended first financial year ending December 2026 or later also uses the new edition. A business failing the screen uses the appropriate K3 route; do not apply the following K2 policies to it. BFN edition dates
The following are hypothetical SEK amounts with no VAT unless explicitly stated; VAT status/amounts are assumed already resolved by the separate VAT method. Account names are illustrative classifications, not prescribed BAS codes. BFN bookkeeping
| Case | Journal and control |
|---|---|
| Invoice and payment | Supported K2 operating-service invoice SEK 12,000 for this year: debit service expense 12,000; credit supplier payable 12,000. On payment debit supplier payable 12,000; credit bank 12,000. Expense is booked once and payable clears. K2 |
| Wrong expense coding | The same invoice was wrongly debited to travel. Separate correction: debit service expense 12,000; credit travel expense 12,000; link original and correction vouchers. Bank/payable do not change. Use the completed/unfinished-period rule above. BFN corrections |
| Unpaid K2 cost | December services received SEK 12,000; invoice arrives January. At close debit service expense 12,000; credit accrued liability 12,000. When invoice is recorded, debit that accrual and credit payable; resolve any estimate difference without duplicating the expense. The item is not below the K2 accrual limit, so it must be accrued. K2 |
| K2 prepaid service | Pay SEK 24,000 for an even service covering December and January; initially debit prepayment 24,000/credit bank 24,000. At December close debit expense 12,000/credit prepayment 12,000, leaving asset 12,000 for January. K2 |
| K2 equipment | Eligible equipment costs SEK 100,000, above the half-price-base-amount limit, enters use at start of a normal full financial year, supported straight-line useful life five years and no residual value. Debit equipment 100,000/credit bank 100,000. Annual debit depreciation 20,000/credit accumulated depreciation 20,000; carrying amount 80,000. Assumptions are illustrative, not a mandatory life or tax method. K2 |
| K1 unpaid sale | Customer paid 100,000 during year; closing unpaid earned invoice 20,000; no opening receivable or advances. Revenue 120,000. Add year-end debit receivable 20,000/credit revenue 20,000; subsequent payment debits bank and clears receivable, not new revenue. K1 |
| Archive expiry | A financial year ends in June 2026. Retain its accounting information through December 2033: count seven calendar years after the calendar year in which it ended. An agreement spanning later financial years can have a later expiry. BFN archive |
Produce a journal, ledger, trial balance, supporting-voucher index, balance reconciliations, open-item list, corrections log and a closing checklist identifying the selected framework, the closing deadline and the still-needed accounting policies. Map ledger balances to the applicable framework’s income-statement and balance-sheet headings; check that each closing figure reconciles to the ledger and its supporting schedule. Use the entity’s approved chart of accounts; no account number establishes VAT liability, deductibility or revenue recognition by itself.
For revenue, obtain the contract, delivery/performance evidence, invoice and any deferred-income schedule. For inventory, obtain count, ownership and cost/valuation evidence. For fixed assets, obtain acquisition documents, commissioning date, useful-life assessment, chosen depreciation policy and disposal records. For tax, payroll and VAT controls, use the separately supported computation and reconcile its liability to postings/payments. When those inputs or a framework decision are missing, mark the relevant closing entry unresolved. Do not fill the gap with an old generic capitalization threshold, tax rate or merchant classification.
These working-paper controls operationalize the requirement to record closing entries establishing the period’s income, expenses and financial position. BFN bookkeeping guide
Facts: A limited company receives a supplier invoice for a business purchase and pays it by bank transfer. The VAT treatment is already separately established.
Method: Retain the invoice as voucher, assign voucher identifier, record the liability/event within the timing rule with documented account coding and period, then post/reconcile the bank payment to the same supplier liability and support. The journal and ledger must expose the voucher identifier, period, coding and amount. BFN source
Facts: A shop takes cash on Saturday and is closed Sunday; the next day work is performed is Monday. It does not record the sales in a certified cash register.
Method: Record the cash receipt in registration order no later than Monday. Preserve the cash-report/voucher trail and reconcile the cash balance. The 50-day deferral does not help here: for cash it covers only the systematic (ledger) presentation, or the registration-order presentation only when the takings are recorded in a certified cash register. BFN source
Facts: A sole trader's annual net turnover is normally at most SEK 3 million, the business is not a financial company, and it has an unpaid customer invoice at year end. Bokföringslagen 5 kap. 2 §
Method: The business may defer ordinary event recording until payment, but must include all unpaid receivables and liabilities at year end before closing. Keep the invoice and other vouchers in order throughout; this is not permission to omit bookkeeping. BFN source
Facts: A March posting was coded to the wrong expense category and discovered in April after March was reconciled.
Method: Do not overwrite/delete it. Post a separate correction in April with its own voucher and clear link to the original, keeping both records readable, and record when and by whom it was made. Assess VAT/PAYE/return amendment separately if the error affected a filed result. BFN source
Facts: A sole trader's turnover is normally at most SEK 3 million and the owner chooses a simplified annual close. A second client is a trading partnership owned by two individuals with the same turnover. BFN, enskilda näringsidkare
Method: Confirm K1 eligibility for the sole trader (a natural person, not a group parent, turnover counted across all businesses) and prepare simplified annual accounts under K1. The partnership prepares annual financial statements under K2/K3 Årsbokslut, not the sole-trader K1. A limited company prepares an annual report and selects K2 only if currently eligible, otherwise K3. BFN, enskilda näringsidkare BFN, handelsbolag BFN, aktiebolag
Facts: Company A has annual net turnover of about SEK 10 million; Company B's turnover is normally at most SEK 3 million. Each receives a supplier invoice on 12 February 2026 and keeps it filed in order. Neither is a cash transaction. BFN source
Method: Company A may book it no later than 50 days after the end of February: 19 April 2026. Company B may use the quarterly rule: 50 days after the end of March, which is 20 May 2026. If either paid in cash from the till, that payment would still be booked in registration order by the next working day. BFN source
Facts: A private AB's financial year ends 31 December 2026. Its meeting adopts the accounts on 15 May 2027.
Method: Certified copies must reach Bolagsverket within one month after adoption, by 15 June 2027. If they have not arrived by 31 July 2027 (seven months after year end), the company pays a SEK 7,500 late-filing fee. If it still does not file, further fees follow: SEK 7,500 two months after notice of that decision, then SEK 15,000 two months after the next notice. ÅRL 8 kap. 3, 6 och 6 a §§
Facts: In 2026 a company scans its paper supplier receipts into its accounting system and wants to shred the paper.
Method: Since 1 July 2024 it may destroy the paper once the scan is a transfer that carries no risk of the information being changed or lost (legible, complete, controlled routine), and it must keep the scanned documents for the rest of the retention period. If the scans are stored with a service in another EU country, notify Skatteverket of the storage place and keep immediate electronic access and printout in Sweden. Bokföringslagen 7 kap. 3 a och 6 §§
